Abstract
A non-contact power distribution system is provided. The system includes a pair of primary conductors defining a pathway and a moving assembly having a pick up coil coupled to the pair of primary conductors through an air gap. The pick up coil has a capacitor in series with the pick up coil, wherein the pick up coil provides power from the pair of primary conductors to the moving assembly to power the moving assembly along the pathway. A transport assembly and a method for obtaining power in a non-contact power transfer system are provided.

16. A method for obtaining power in a non-contact power transfer system, comprising:
-
obtaining power from a primary coil through a secondary coil, wherein the primary coil and the secondary coil are separated by an air gap;
transferring the power through the secondary coil efficiently, the transferring including, matching a magnitude of the impedance due to the leakage inductance with a capacitor placed in series with the secondary coil; and
powering a moving assembly with the transferred power. - View Dependent Claims (17, 18)
